Some projects linger in the pipeline long after their expected value has fallen too far to justify continued investment. They still consume budget, leadership attention, and workload bandwidth, but they no longer have a realistic path to meaningful outcomes. These zombie projects—they look like legitimate efforts but lack everything that makes an initiative worthwhile—quietly erode your project portfolio’s ROI.

It isn’t that business leaders deliberately choose to keep these stale initiatives around. Most zombie projects survive because no one stops to ask whether they’re still valuable or if the work still deserves support.

The project pace in many organizations is quite high, and there’s little opportunity to reevaluate efforts that have fallen off the active list. Over time, zombie projects drag on the portfolio. The problem compounds when stronger initiatives must compete for the same funding and resources that are going to weaker efforts.

If you suspect there are zombie projects lurking in your portfolio, use these steps to identify them and decide their fate.

Begin by defining project health

Before you can flag zombie projects, the business needs a shared definition of what a healthy project looks like. An established framework helps to expose projects that remain in the pipeline because of history, not because they still have an articulable business case.

Some baseline criteria can help you quickly surface the most obvious warning signs:

• Are the project’s expected benefits still important to the organization?
• Is the project actively sponsored? If supporters have already walked away, the project may not be worth resuscitating.
• Are the current cost, timeline, and scope still realistic and valid?
• If this project came along today, would business leaders approve it?

Healthy projects share several core traits:

• An expected return that justifies the investment and associated risk.
• Clear outcomes that continue to hold measurable and meaningful value.
• Active support from involved sponsors, influencers, and advocates.
• Connections to the organization’s current strategic priorities and overall mission.

New information, changing priorities, or additional clarity around value can all influence a project’s health over time.

Use data to drill down

Zombie projects sometimes overlap with pet projects—those initiatives that exist because a powerful stakeholder has an attachment to the work that’s out of sync with the project’s business relevance or value. Signals such as chronic schedule slips, repeated scope creep, and ongoing budget draw without corresponding progress can be reviewed objectively at the data level. This approach eliminates personal agendas and gut feelings from the evaluation process.

Rather than trying to do a deep dive into every project in the portfolio, a data-driven review helps focus attention on initiatives that are pulling resources without showing commensurate results.

Put structure around the decision-making process

If a project that lacks a clear purpose or value is still part of the portfolio, then something in the organization’s governance or control structure has already broken down. Establishing a clear framework to guide decisions about these zombie projects can help leadership move them out of limbo. A strong evaluation process is supported by revisiting the effort’s original business case. Is it still relevant? What has changed since the project was originally approved?

Keep the options available to decision makers simple and realistic.

• End the project if the business case is too weak to justify continuing.
• Reduce the scope to focus on one or a very small set of value-driven outcomes.
• Reassign the project’s resources and useful deliverables to another effort in the portfolio that’s already in a healthier state.

Inaction leaves zombie projects in place but following a deliberate process helps to guide business leaders through to a clear decision.

FAQ

What is a zombie project?

A zombie project is an initiative that continues consuming organizational resources despite lacking meaningful progress, strategic relevance, executive sponsorship, or a realistic path to delivering business value.

Why do zombie projects remain active?

Zombie projects often survive because organizations avoid reevaluating older initiatives, lack governance accountability, or continue funding projects based on historical investment rather than future value.

How can organizations identify zombie projects early?

Organizations can identify zombie projects by monitoring metrics such as schedule delays, budget overruns, low stakeholder engagement, declining strategic alignment, and weak milestone completion rates.

Should every struggling project be canceled?

Not necessarily. Some projects may still provide value if their scope is reduced or resources are reassigned strategically. The goal is to maximize portfolio ROI, not simply eliminate projects.

How does portfolio governance improve ROI?

Strong portfolio governance improves ROI by ensuring organizational resources remain focused on initiatives that align with strategic priorities and deliver measurable business outcomes.
